For a further understanding of the invention, its role, the technical means employed, and the efficacy attained by its cooperation, it is believed that the invention will be more fully and specifically understood from the following description.

As shown in fig. 1, when the components of the ceiling fan motor cover 100 are completely manufactured and are not assembled yet, the positioning member 23 extends along the vertical axis X to form a straight plate (as shown by the solid lines in fig. 1 and the phantom lines in fig. 3), and the positioning end 232 can be drilled with the through hole 233.

As shown in fig. 2 and 3, when the ceiling fan motor outer cover 100 is to be covered and assembled outside the ceiling fan motor unit 1, an operator firstly sleeves the bearings 105 on the upper shaft hole 221 and the lower shaft hole 16, and then passes the shaft rod 104 of the stator 101 through the bearings 105, so that the housing base member 10 and the housing cover member 20 are mutually matched, and the stator body 103 corresponds to the rotor 102 pre-fixed on the inner side surface 211 of the housing cover member 20, so that the housing cover member 20 can smoothly rotate relative to the stator 101.

Next, when the housing base 10 is to be assembled with the housing cover 20, the operator aligns the groove 15 with the positioning member 23 and fits the housing base 10 to the housing cover 20 along the axis L until the narrow section 132 fits inside the housing cover 20 and the narrow section 132 is opposite to the inner side 211. Then, the positioning member 23 is bent from a straight plate shape (as shown in fig. 1, 3, solid lines) into an L shape (as shown in fig. 1, 2, 3, solid lines), and the positioning end 232 abuts against the bottom surface 11, so that the through holes 233 are aligned with the screw holes 14, respectively, and the operator can use the locking member 30 to pass through the through holes 233 and screw-lock in the screw holes 14, so that the housing base member 10 is locked to the housing cover member 20, and the ceiling fan motor outer cover 100 is positioned relative to the ceiling fan motor unit 1.

Next, the efficacy of the present invention is summarized as follows:

firstly, because the screw holes 14 are positioned on the bottom surfaces 11 of the same plane, the screw holes 14 can be simultaneously processed, the processing procedure of the screw holes 14 is simplified, the processing time is short, and the processing error can be avoided.

Secondly, the housing member 20 utilizes the arrangement of the cutting groove 214, so that the positioning member 23 can absorb the offset when being bent into an L shape from a straight plate, and the through hole 233 of each positioning member 23 can accurately correspond to the screw hole 14, the drilling position of the through hole 233 does not need to be controlled absolutely precisely, the through hole 233 is easy to process, the screwing operation of the locking member 30 is also easy, and the assembly of the housing member 10 and the housing member 20 is easy.

Thirdly, the groove 15 is formed by the housing base member 10, and when the housing base member 10 is assembled with the housing cover member 20, the positioning member 23 is embedded by the groove 15, so that the assembly of the housing base member 10 and the housing cover member 20 is relatively easy.

In conclusion, the outer cover of the ceiling fan motor has simple integral structure and easy manufacture and assembly, can reduce the production cost and can really achieve the aim of the invention.
